MBD is the unit responsible for Office 365 as well as the regular Office software. Microsoft says when you eliminate certain short-term items, like its Office Upgrade Offer, the unit posted non-GAAP revenue growth of 3%.

But it credits that growth to Microsoft's regular software, noting that these server products experienced double-digit revenue growth.

Where does that leave the Office cloud? In a fog.

Note: Don't confuse "Office 365" with the confusingly named " Office 365 Home Premium edition." Home Premium is not a cloud version of Office. It is the latest version of the Office software, known as Office 2013, paid for on an annual subscription basis.
